[javasim-general] howto use wait_until?

[Hung-ying Tyan]

Peter,

I agree with you.  I have another solution here you can try.
A small class I wrote is called WaitUntil and you can use it as:

	for {set i 0} {$i<100} {incr i} {
	  # set parameters
	  run experiment
	  rt experiment stopAt 120000
	  # wait for runtime to stop
	  java::new WaitUtil [rt -q experiment]
	  # log results
	  reboot experiment
	}

The class is attached below.  Thanks for your feedback.

===================================================
public class WaitUntil extends Thread
{
	drcl.comp.ACARuntime runtime;
	boolean done = false;

	public WaitUntil(drcl.comp.ACARuntime r) throws InterruptedException
	{
		runtime = r;
		synchronized (this) {
			start();
			if (!done)
				this.wait(); // wait until the runtime stops
		}
	}

	public void run()
	{
		while (!runtime.isStopped()) {
			yield();
		}
		synchronized (this) {
			done = true;
			this.notify(); // notify the main thread
		}
	}
}
